About the event

If you’re only ever going to do one marathon, make sure it’s the TCS London Marathon. 

From the cheering crowds and thrilling atmosphere to the world-famous landmarks lining the 26.2-mile route from Greenwich to the Mall, it’s no surprise that this is one of the most famous races in the world. 

Run the TCS London Marathon with Team JDRF in 2025 and make every mile count by doing something amazing to help those living with type 1 diabetes. 

In 2025 JDRF aims to have around 200 runners taking part in the TCS London Marathon, helping us to reach our goal of a combined total of £450,000 to fund type 1 diabetes research.
